ContentDocumentLink insertion fails

Question

I want to share all records with admin user using next trigger:

trigger ContentVersionTrigger on ContentVersion (after insert) {
    system.debug('sdfsdf' + Trigger.new);
    for (ContentVersion item : Trigger.new) {

        ContentDocumentLink link = new ContentDocumentLink();
        link.LinkedEntityId = Id.valueOf('005E0000007Sew5IAC');
        link.ContentDocumentId = item.ContentDocumentId;
        link.ShareType = 'V';
        link.Visibility = 'AllUsers';
        insert link;

    }

}

It throws next exception:

Insert failed. First exception on row 0; first error: INSUFFICIENT_ACCESS_OR_READONLY, Invalid sharing type V: [ShareType]

Who knows how to fix it?

Update: If I use 'I' instead of 'V' I have another error:

Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, Document with ID: 0690L000003rtLV is already linked with the entity with ID: 005E0000007Sew5: Linked Entity ID: [LinkedEntityId]

But it's not true, such record doesn't exist

Answer 1

Using visibility to all users:

link.Visibility = 'AllUsers';

You should also set the share type to this:

link.ShareType = 'I';

Which means:

Inferred permission. The user’s permission is determined by the related record. For shares with a library, this is defined by the permissions the user has in that library.

I think you are already success，move insert out of the loop ,try to use a list for insert, and donot hardcode the Id Try another time

trigger ContentVersionTrigger on ContentVersion (after insert) {
    system.debug('sdfsdf' + Trigger.new);
    List <ContentDocumentLink> ContentDocumentLinkList = New 
     List <ContentDocumentLink>();
    for (ContentVersion item : Trigger.new) {

        ContentDocumentLink link = new ContentDocumentLink();
        //should be Unique
        link.LinkedEntityId = Id.valueOf('005E0000007Sew5IAC');
        link.ContentDocumentId = item.ContentDocumentId;
        link.ShareType = 'V';
        link.Visibility = 'AllUsers';
        ContentDocumentLinkList.add(link);
        //insert link;

    }
    insert ContentDocumentLinkList;
}

It sounds like from the exception, INSUFFICIENT_ACCESS_OR_READONLY, that you do not have the correct permissions to access ShareType. I would look at the profile or permission set that your user has and check that field t make sure that it has write access.
